The process of separating membranes productivity growth during treatment with gas-discharge plasma ions has been investigated and a method of polymer and metal-ceramic membranes modification by plasma-chemical treatment has been developed. The method allows to obtain membranes with required pore sizes. Plasma treatment of a metal-ceramic membrane with vapors of heterorganic compounds leads to a decrease in the pore size in the surface layer up to 250Ǻ. The use of plasma-modified metal-ceramic and ceramic membranes in the processes of gas purification from solid impurities makes it possible to realize an effective phase separation.
The process of increasing the performance of separating membranes by their treatment with plasma ions of gas discharge has been studied and the method of modification of polymeric and metal-ceramic membranes by plasma-chemical influence, which allows to obtain membranes with controlled pore size, has been developed. Treatment in plasma with vapor of organometallic compounds of metal-ceramic membranes leads to reduction of the pore size in the surface layer up to 250 Å.
